All my oscillators are still acting weird, but I had a Doepfer Dual Quantizer come in yesterday after being on backorder for a while. And what a perfect module to receive while having tuning issues.

Ok, if you're knowledgeable about modular synths and/or circuits in general and you have the time to help me troubleshoot unstable pitches on multiple oscillators, I'd really appreciate it. Info below the break due to having a lot of context from prior troubleshooting to go through. So anyway here's the sich:

Behavior:

- Pitch is wobbling back and forth at varying speeds. Sometimes trending upwards, sometimes staying within a certain margin. Usually the wobble is very small (changing at a rate of around 0.1Hz/s) but sometimes its much more noticeable. Even when unnoticeable at first, everything is of course still slowly being detuned over time.

What is exhibiting the behavior:

- Instruo Ts-L

- Pittsburgh Modular Local Parks

- Makenoise Maths (only tested when turned up to audio frequency)

- Moog Mother 32's oscillator

- Moog DFAM's oscillators

Setup:

Local Parks, Ts-L, and Maths have been together in a a Tiptop Audio Mantis, using its built-in power supply and provided power brick. A sticker on the back of the Mantis says "13v", and while the power brick is 12v, it had been working up until now, and did come with the case. The Mother 32 and DFAM have been in their provided cases from Moog, and have been powered via the provided DC adapter. A 4ms Pod64x was used in troubleshooting as well, which has been using its built in power supply and the provided 15v power brick.

Circumstances:

Testing has been done on a Mordax Data. The Local Parks, Ts-L and Maths have been plugged into the same case for some time now. That case has been consistently plugged in but powered off. After several months of hiatus, I booted it up and noticed an audibly unstable pitch. There were several thunderstorms in the weeks prior, resulting in the power going out a couple times. The two Moog simi-modular synths had been unplugged for those several months until I plugged them back in for testing this problem.

Data points from troubleshooting:

(Testing was done using the Mordax Data's tuner and voltage monitor features.)

- Wobble persists after moving the three non-moog modules from the Mantis to the Pod64x, testing together as well as one at a time

- Persists after changing the ribbon cables

- Persists after changing which header in each case they were plugged into

- Persists across multiple power outlets in different areas of the house.

- Persists when testing the Ts-L in an outlet in another house.

- Persists across multiple wave outputs on each oscillator

- The attenuverters on Maths and the "mix" (attenuator) on the Mother 32 both output a constant voltage

- Using the v/oct input transposes the pitch correctly, but the wobble doesnt go away.

- If i let the pitch drift and then power the case off and back on, the pitch will return to its original tuning before the drift

- As emphasis: the two Moog synths were in no way connected to my main eurorack case. Neither by power or patch cables

- Yesterday I tried unplugging the Data, but the change in pitch at the time was too small to be noticable (showed on Data as changing every half second in increments of .01Hz.)

Im kinda at a loss at this point. I asked about it in the r/modular subreddit, and someone said they had the same issue with their Mother 32 when it was underpowered, but i know for sure that the Pod64x and Moog synths are sufficiently powered. I tried two different houses, but they both use the same utility company? If the problem is the utility company for the entire area, I feel like I wouldnt be the first person to learn about this. Idk man im stumped. If anyone has any insight, I'd be really grateful. I just wanna make (in-tune) music again, man.

How do people manage two different tumblr accounts without reblogging to the wrong one constantly? Anyways, i didnt mean to reblog that giant post explaining how the public school fitness program was designed as military training for children to this blog. that was for my main blog. My b.

We have envelope! Just a simple attack release, but as y'all can maybe tell from the picture, I've got room for three separate generators. Now I just need some VCAs and filters for them to drive 😅
